In mathematics, planar algebras first appeared in the work of Vaughan Jones on the standard invariant of a II1 subfactor [1]. They also provide an appropriate algebraic framework for many knot invariants (in particular the Jones polynomial), and have been used in describing the properties of Khovanov homology with respect to tangle composition [2] [3].
